It would be worse if you had 3.73s. The lower the ratio (bigger number), the more power to the rear wheels but worse mileage.

Is there anything on this Site with what the RPO codes mean?
I got the answer to my original Post here. But I was just wondering about the 6 Columns of Codes and what that all means.

Actually, you can find the gear ratio from the VIN. It just isn't part of the VIN, but rather, needs an application to look up the RPO codes for that VIN. CompNine.com has such an application in their VIN Decoder.

The list is a list of all of the options installed on your truck.

If you find out that they are 3.42s let me know. Ive got my stock ones laying around that you can have for shipping.
